Overview
The remnants of Tropical Storm Gordon interacted with a surface front to produce widespread heavy rain across much of central Indiana. Rainfall amounts between 4 and 6 inches were common. This caused some Flash Flooding in the southern part of the area, and more general flooding at other locations.Flooding
The heavy rain caused many streams to flood quickly, and then for rivers to flood soon thereafter. Most flooding remained in the Minor Category, but some rivers reached Moderate. Below are just a few examples of flooded rivers.

Environment
The remnants of Tropical Storm Gordon interacted with a surface front. The moisture content of the atmosphere was very high. Precipitable water, a measure of moisture content in the atmosphere, is normally around 1 inch for early September in Indiana. Amounts approached 2 inches for parts of the area on September 8.
